The HTML5 intellisense includes support for the following features:
- WAI-ARIA – an accessibility standard
- Microdata – semantic markup language
- Fixes for the video and audio tags
- New input types like email, URL, date
- Drag & Drop
The update brings intellisense for many CSS3 features including Multi-columns, Border-Radius, Animation, Transitions and Transforms. Scott Hanselman’s blog post contains a complete list of features supported.
The Web Platform and Tools team plans on releasing such updates regularly, and it is expected Microsoft will speed up the process of creating the best HTML5 tools on the market since it is now clear they are deeply committed to web technologies following the announcement that the next Windows will wear HTML5 clothing.
